Pretty much. What we like to think of as USB-C are actually 3 individual parts that an be swapped around as the OEMs feel like. there is the 3.1 bus speed, that can be swapped for older and slower speeds. There is the Power Delivery spec, that can be replaced with older or omitted entirely. And then there is the C plug itself, that can be replace with an A or B plug when mixed with any of the above. The only thing that the C plug offer on its own is hte aux pins that can be used to carry Displayport, HDMI or Thunderbolt signals. But again this depends on the OEM. It is a downright combinatorial explosion, that is just waiting to set fire to something. Hell, a while back there was a story about someone getting their phone drained because the C port allows bi-directional power delivery. And their powerpack used the C port for both charging itself and charging other devices. This, in combo with a phone that could charge other devices as an emergency option, allowed the two devices to ping pong a charge between them until both were run dry. Frankly the C plug and related specs are overdesigned, trying to be all things to all people.
